/ 173 GRAVIMETRIC PARTICULATE MATTER MEASUREMENT WITH PARTIAL FLOW DILUTION AVL Smart Sampler The AVL Smart Sampler is a part ial �� ow dilution system used in gravimetric part iculate matter sampling from internal com��ustion engines in accordance with ISO 16183, 40-CFR 1065 , 1066 and al l other relevant global regulations. MEASUREMENT PRINCIPLE A partial �� ow dilution system such as the AVL Smart Sampler mi��es and dilutes a small sample of the e��haust �� ow with air under controlled conditions. This allows particulates to form in a repeata��le manner simulating reactions in the atmosphere. The system samples the diluted e��haust over a fi lter medium where the particulates are captured and can su��se��uently ��e weighed. The �� e��i��le design also allows the AVL Smart Sampler to ��e used as a diluter for particle counting according to ECE regulation No 49 and ��lo��al Technical Regulation No 4. For particle counting, the system operates as it does for gravimetric measurement with a proportional sample of the diluted exhaust diverted to an optional particle counting device. A new fi eld is the certifi cation of passenger cars on chassis dynamometers according to US 40-CFR part 1066. APPLICATION The Smart Sampler can ��e used instead of a CVS for Euro III to VI certifi cation, and, with the addition of the ��add-on sampling�� option, it also provides other testing devices like particle counters with diluted exhaust samples. The option of high pressure testing allows the Smart Sampler to be used at pressures as high as 1,000 milli��ar ��gauge��, and this makes it the perfect tool for effi ciency evaluations and the optimization of ��PF systems. The Smart Sampler can also ��e used for analyzing the in�� uence of different fuels on PM emissions. The same Smart Sampler is suita��le for sampling everything from small porta��le engines to the largest engines and can easily ��e moved ��etween test cells for ma��imum �� e��i��ility. BENEFITS AT A GLANCE �� Fulfi lls all relevant regulations �� Fast warm up time�� Smart Sampler is ready for operation in 15 minutes from a cold start. �� With the optional add-on sampling, the Smart Sampler acts as a diluter for particle counting applications. • Modularity of components allows for simple structuring of options; future upgrades are simple and can be done at the customer’s site. • Rapid set up time for quick test cell changeovers �� Automatic Filter Changer for up to 20 PM fi lters. Above: Due to the small and modular design of the Smart Sampler, it can be placed even in smallest test cells Left: The Smart Sampler‘s software is intuitive and easy to use
